PALMER, KENNEDY, OF TACOMA, VIASHINGTON.

CUTTING DEVICE.`

vApplication led January 15, 1921. Serial No. 437,435.

T all whom t may concern Be it known that I, PALMER KENNEDY, a citizenof the United States, residing at Tacoma, in the county of Pierce andState of Washington, have invented certain new and useful Improvementsin Cutting Devices, of which the following .is a specification.

My said invention relates to an improved holder for Vsafety razor bladesand it 1s in-l tended to be used as a ripping vdevice by seamstressesand for other purposes that will suggest themselves to the user.

The main object of myinvention is to provide a device of the classdescribed which shallbe simple and` which may be produced in a veryeconomical manner.

A' further object of my invention is to providefa device of thecharacter described in which-'the blade may be very -readily removed andreplaced.

Referring to the accompanying drawing which is made a part hereof and onwhich similar reference characters indicate similarparts, l

Figure 1 is a plan of one form of my invention,

Figure 2, a section on line 2-2, Figure 3, a. modied form, and Figure 4is a section on lineV /1-4 ure 3. v I f Figure is a furthermodification, and Figure 6 a section on line 6-6 thereof.

Figures 7 to 12 show additional modifications.

In Figure a handle portion 14C' and al blade 15 herein shown kas beingof the Gillette type but which may be of any type so formed as to beconveniently retained in place by the holding devices on the handle 14C.In Figure 1 these holding devices comprise a flap 16 punched out fromthe forward end of the device leaving a portion 17 underneath the Hap onwhich the same may rest. Preferably the flap 16 has projections 18formed in the stamping operation which may be bent downwardly to engagethe opening or openings in the blade to prevent accidental removalthereof. The flap is beveled underneath its lower edge to enable theuser to insert a fingernail or the like under the flap to lift the same,as shown in Figure 2.

In Figure 3 the portion 17 underneath the blade 15 is continuous withthe handle and the flap 16 is bent over to enclose and of Fig- 1 I haveshown a device having form a guard for the upper edge of the blade. rlheportion underneath vthe bladek has punched up lugs 19 for engaging theopening `or openings in the blade and the blade is held in place by thelugs and by the pressure of the resilient'flap 167'. At its rearl endthe flap has a projection 2O which forms a thumb piece whereby theusermay lift the iap so that the blade may. be readily'ref moved.

In the modification of Figure A5 the fiap 16 is formed, as inFigure 3,by an integral continuation ofthe back 17 and is cut away to vleave atriangular portion, the eX- treme end of which extendsdown to the centerhole inthe blade. It may, if desired, paye a tang 18 extending `downinto the io e.

The modification of Figure7 shows a holder flat throughout its entireextent and provided with a pair ofstamped lugs 1 9.

Cooperating with these lugslfor holding the blade is a screw 21 passingthrough the blade and into a threaded orifice in the holder. If desiredthe screw may pass through the holder and be held in place by ainut,instead oftaking the form shown. r

In Figure 8 is shown a-modification' similar to, that of Figure 7,except thattwo holes are formed vinthe holderin place of the lugs and apair of screws 21'` are inserted therein.

The screws may-be threaded into Athe holder. as .in Figure 7, instead ofbeinggprovided with nuts, if desired. It will be understood that theholes or screw threaded apertures in they handle are preferably providedyat such-a distance aparty that if a blade such as the Durham Duplextype is used theholes will fall at the ends of the openings in the bladeso that the blade will be. held against endwise movement. j

Figure 9 shows a device similar to Figure 8, a pair of paper clips of awell-known type being substituted for the screws. These clips are merelyinserted from the underside and have their legs spread apart and bentoverto hold the blade in place. y

Figure 10 shows a further modificationin which the end of the holder islbent over at 23 and a part 24 is also stamped out of the holder andbent over to engage the blade or to project into the opening thereof asdesired. The part 23 may also bear yieldingly n Y shown and described.

In Figure 1l I have provided a holder with lugs 19 and turn-buttons 25co-acting therewith to hold the blade in place.

Figure 12 shows a device in which the stamped out lugs are carriedfarther up than in other forms, somewhat as in the wellknown glovefastener. Cooperating with these lugs to hold the blade in place is aslip of metal 26 having openings 27 surrounded by resilient tongueswhich snap over the lugs 19, the slip 26 then resting closely againstthe blade.

Many modifications of my device will suggest themselves to those skilledin the art and I do not limit myself to what is herein For example, inthe device shown in Figure l2 I may provide a single central lug with asnap holder therefor and one or more lugs engaging the blade to preventrotation of `,the blade. IV

may also provide in any such device as those shown in Figures '7 to l2,a curved guard such as 16 of Figure 5 which may, if desired, extend onlyfar enough over to c.om pletely cover and' pro-tect the edge of theblade. It will be seen that the devices shown in the drawing are merelyillustrative, the true scopeI of the invention being defined' by theappendedr claims. Y

Having thus fully described my said invention, what I claim as new anddesire to secure by Iietters'Patent, is: f

l. Ina cutting device a two-edged safety razor blade and a one-pieceholder thereforl having a'handle and lalso having a punchedout portionapproximately equal in length to the blade, said portion extendingloverthe blade to hold the same in place and having lugs at its free 'endextending into holes in the blade to prevent rotation thereof,

substantially as set forth.

2. In a cutting device, a safetyrazor blade and a holder therefor havinga handle and also having a laterally extending punchedout portionextending over the blade to hold the same in place, and providing aguard for one edge of the blade, said portion being beveled underneathits lower edge, substantially as set forth.

3. In a cutting device, a safety razor blade and a handle thereforhaving a punched-out portion extending over the blade to hold the samein place, said punched out portion having` one or more projections atits forward end extending transversely into corresponding openings intheblade to prevent accidental removal thereof, substantially as set forth.

t. A cutting instrument comprising a twoedged safety razor blade and -aholder therefor having a face-against which the blade may rest, aresilient portion 'punched out from the said face engaging the oppositeface of the blade to hold it in place and forming a guard for one edgeof the blade, and one or more lugs on the resilient portion to engagecorresponding holes in 'theblade to prevent displacement thereof,substantially as set forth. f v

5. A cutting instrument comprising a twoedged safety razor blade and aholder hav-` ing a handle said holder having a face against which thevblade may rest-,the side edges of the holder and handle being parallelto the cutting edges of the blade, a resilient extension engaging theopposite'face of the blade and forming a guard for one edge of theblade, the other edge vof theblade overhanging the adjacent edge oftheholder and one or more lugs on the .extension tov engage correspondingholes in the blade and preventV displacement thereof, substantially asset forth.

6. A oneepiece holder for a two-edged t F. W. DAHN, M. A. SHAW.
